TTN, likewise on a four-engined fighter squadron somewhere in Scotland - although our CO had already entered us all on the next B exam, in one months time! Much midnight oil was burned. The day before the exam a Mickey Finn/taceval was called, and after twelve hours over the North Atlantic we were diverted to Machrihanish so I missed the exam. I think it was two weeks later the B exam was abolished and I became an instant Flt Lt, so the Boss immediately enrolled us all for the next C exams.
